  1. 1. Improved Neuropeptide Identification : Bioinformatics and Mass Spectrometry

    Author : Maria Fälth Savitski; Per Andrén; David Fenyö; Per Svenningsson; Ronald Beavis; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; neuropepides; database; peptide identification; peptide fragmentation; mass spectrometry; tandem mass spectromerty; Bioinformatics; Bioinformatik;

    Abstract : Bioinformatic methods were developed for improved identification of endogenous peptides using mass spectrometry. As a framework for these methods, a database for endogenous peptides, SwePep, was created. It was designed for storing information about endogenous peptides including tandem mass spectra. READ MORE

  2. 2. Development and Application of Software Tools for Mass Spectrometry Imaging

    Author : Patrik Källback; Per E. Andrén; Per Svenningsson; Anna Nilsson; Benjamin Bowen; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry imaging; MALDI; DESI; msIQuant; quantitation; neurotransmitters; drugs; derivatization; brain; compression; data entropy reduction;

    Abstract : Mass spectrometry imaging (MSI) has been extensively used to produce qualitative maps of distributions of proteins, peptides, lipids, neurotransmitters, small molecule pharmaceuticals and their metabolites directly in biological tissue sections. Moreover, during the last 10 years, there has been growing demand to quantify target compounds in tissue sections of various organs. READ MORE

  3. 3. Neuropeptidomics – Methods and Applications

    Author : Karl Sköld; Per E Andrén; Per Svenningsson; Chris Shaw; Uppsala universitet; []
    Keywords : Pharmaceutical pharmacology; mass spectrometry; proteomics; peptidomics; neuropeptide; bioinformatics; Farmaceutisk farmakologi;

    Abstract : The sequencing of genomes has caused a growing demand for functional analysis of gene products. This research field named proteomics is derived from the term proteome, which by analogy to genome is defined as all proteins expressed by a cell or a tissue. READ MORE

  4. 4. Neuropeptidomics – Expanding Proteomics Downwards

    Author : Marcus Svensson; Per Andrén; Per Svenningsson; Jonathan Sweedler; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; proteomics; peptidomics; mass spectrometry; neuropeptide; chromatography; Farmaceutisk farmakologi; PHARMACY; FARMACI;

    Abstract : Biological function is mainly carried out by a dynamic population of proteins which may be used as markers for disease diagnosis, prognosis, and as a guide for effective treatment. In analogy to genomics, the study of proteins is called proteomics and it is generally performed by two-dimensional gel electrophoresis and mass spectrometric methods. READ MORE

  5. 5. Striatal adenosine A2A receptors

    Author : Per Svenningsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; caffeine; adenosine; A2A receptors; dopamine receptors; striatum; basal ganglia; immediate early genes; c-fos; NGFI-A; DARPP-32; in situ hybridization;

    Abstract : The nucleoside adenosine exerts a modulatory action in the central nervous system by activating G-protein coupled receptors. Four such receptors are cloned and pharmacologically characterized: A1, A2A, A2B and A3. Caffeine, the most widely consumed psychostimulant, acts as an adenosine receptor antagonist predominantly on the first two. READ MORE
